BorgWarner S364SX-E – 64.47mm S300SX-E 8780
Utilizing the latest generation 64.47mm billet EFR compressor wheel aerodynamics with uprated 360 degree thrust assemblies, the all new ‘SX-Enhanced’ turbos redefine performance and value for modern turbochargers.
This proven design is packaged in a purpose built SX-E compressor housing with ported-shroud inlet and speed sensor port. It is paired with traditional Airwerks 80mm Inconel Turbine and Flexible Housing options. The 64.47mm S300SX-E Turbo has smaller overall dimensions than the EFR8374 and higher airflow rates, which make this an excellent match for high-boost and high-power 64.47mm drag racing applications. Thermals are taken care of by an Oil-Cooled Journal Bearing only.

Install
Application Notes:
- 3AN oil feed line is recommended. If -4AN or larger is used, an oil restrictor is required (just like GT turbos)
- Full-Race recommends upgrading to a .91 A/R modified to 3″ V-band for Twinscroll applications up to 20psi boost.
- Full-Race recommends upgrading to a 1.00 A/R modified to 3″ V-band for Twinscroll applications up to 25 psi boost.

Additional Information:
- Max warm oil pressure: 5 bar (73.5psi)
- Max cold oil pressure: 8 bar (118psi)
- When starting a fresh engine build or in extremely cold climates – oil pressure must reach 0.5bar (7.2psi) within 4 seconds maximum.
- Do not load the engine with full boost and WOT until full operating oil pressure is present
- Do not load the engine with full boost and WOT if any boost leaks are present (this can result in turbocharger overspeed)
